Forget weirdly-shaped silicone battery cases: The biggest new Apple product is, in fact, a revamp of the company's Lightning to SD Card Camera Reader. Not only does it now offer USB 3 speeds for the iPad Pro, but all iPhone models post-iPhone 5 are supported, too.
First reported by Jeff Benjamin at iDownloadBlog, this is a huge boon for anyone who travels with a DSLR (or takes professional photographs)—no longer do you need an iPad or Mac to save photographs or video you've snapped to iCloud Photo Library or Dropbox, or share images with friends. I've been asking for this capability since the release of Apple's original SD card reader, and I am beyond excited to get my hands on it.
